Method for water treatment and recycling

A method for treating contaminated water containing a carbonaceous and/or nitrogenous compound, comprising:

• passing the contaminated water through a water treatment system to obtain an effluent having a reduced content of the carbonaceous and/or nitrogenous compound relative to the contaminated water;
• wherein the water treatment system comprises:
• a waste water treatment structure,
• a septic tank and/or a solids separation device upstream and in fluid communication with the water treatment structure, and
• a discharge tank downstream and in fluid communication with the waste water treatment structure;
• wherein the waste water treatment structure comprises
• a first geotextile fabric layer;
• a second geotextile fabric layer;
• a third geotextile fabric layer;
• a first filler layer comprising plastic particles, arranged between the first and second geotextile fabric layers;
• and
• a second filler layer comprising plastic particles, arranged between the second and third geotextile fabric layers, and
• an aeration tank under the first second and third fabric layers and the first and second filler layers,
• wherein the first, second, and/or third geotextile fabric layer comprises at least 75 wt. %, relative to total fabric layer weight, of a nonwoven fabric comprising at least 75 wt %, relative to total nonwoven fabric weight, of polypropylene or polyethylene terephthalate,
• wherein the aeration tank, geotextile fabric layers and the filler layers are vertically stacked within a housing, and
• wherein the waste water treatment structure is configured such that contaminated water proceeds sequentially through the aeration tank, the first geotextile fabric layer, the first filler layer, the second geotextile fabric layer, the second filler layer, and the third geotextile fabric layer.
